1. a sensing apparatus (1), is particularly useful for the rolling ring (2) of quenching vehicle hub-bearing unit outer ring (3), comprises:

  • -at least one pair of block be made up of electro-conductive material (4,5), it is mechanically connected each other and is electrically insulated from each other;

    -at least one block be made up of electrically insulating material (8), it is upper and support respective ruhmkorff coil (9,10) that it is mechanically connected to block (4,5) that this electro-conductive material makes;

    -the first hydraulic circuit (11), its part is positioned at the block (4 that this electro-conductive material is made,

         5) in and each pipe extension (12 by being made up of electro-conductive material of part, 13,14) obtain, each pipe extension is positioned at the outside of the block (4,5) that this electro-conductive material is made and the block made with fluid tight manner and electro-conductive material in side is mechanically connected, and be mechanically connected at opposite side and this ruhmkorff coil (9,10);

    Wherein, this first hydraulic circuit (11) comprises at least one first branch road (15) for cooling fluid being supplied to this ruhmkorff coil (9,10) and at least one second branch road (16) for this cooling fluid being discharged from this ruhmkorff coil;

    It is characterized in that, combination has;

    I) all ruhmkorff coils of hydraulic parallel (9,10) and the first branch road (15) be linked in sequence each other;

    Ii) only by second branch road (16) of the first ruhmkorff coil (9) with the first bypass outlet (17) hydraulic connecting of this first hydraulic circuit;

    Iii) the first hydraulic circuit (11) comprises at least one the 3rd branch road (19) for each ruhmkorff coil (10) except the first coil (9), each 3rd branch road (19) comprises the second bypass outlet (20) exporting (17) with first and be separated, and with unique ruhmkorff coil (10) hydraulic connecting except the first coil.
